In this chapter, precision manufacturing processes for the large-size rotary table, spindle, and guideways were analyzed and concluded. Firstly, specifications of typical components were listed as well as the design principles. Cases for the slide guideways, air rotary table, and spindle were given separately. The investigation mainly focuses on the aerostatic and hydrostatic bearing components which are generally customized, the design strategies, critical dimensions measuring techniques, material selection method, and machining procedure will be introduced compressively.
